A sprayable polymeric scaffold composition for localized anti-inflammatory therapy is disclosed. The composition comprises lipid nanorods encapsulating inflammasome inhibitors, a thermogelling agent, and a thickening agent. The lipid nanorods, which can be formed using pyridoxine dipalmitate and DSPE-PEG (2000) carboxylic acid, inhibit NLRP3 and AIM2 inflammasomes, reducing inflammation. The thermogelling agent, such as poloxamer 407, enables the composition to transition from a fluid sol state at room temperature to a semi-solid gel state at body temperature, forming a localized gel film upon topical application. The thickening agent, such as mucin, enhances viscosity and provides additional anti-inflammatory effects. The composition delivers sustained release of encapsulated inhibitors, effectively reducing inflammatory markers and symptoms in conditions such as psoriasis. The sprayable scaffold offers a novel, localized treatment platform with improved skin penetration, ease of administration, and reduced systemic side effects.
